#
# generate a .def file
#
# It does this by parsing the header files and looking for the
# prototyped functions: it then prunes the output.
#
# Intermediary files are created, call libeay.num and ssleay.num,...
# Previously, they had the following format:
#
# routine-name nnnn
#
# But that isn't enough for a number of reasons, the first on being that
# this format is (needlessly) very Win32-centric, and even then...
# One of the biggest problems is that there's no information about what
# routines should actually be used, which varies with what crypto algorithms
# are disabled. Also, some operating systems (for example VMS with VAX C)
# need to keep track of the global variables as well as the functions.
#
# So, a remake of this script is done so as to include information on the
# kind of symbol it is (function or variable) and what algorithms they're
# part of. This will allow easy translating to .def files or the corresponding
# file in other operating systems (a .opt file for VMS, possibly with a .mar
# file).
#
# The format now becomes:
#
# routine-name nnnn info
#
# and the "info" part is actually a colon-separated string of fields with
# the following meaning:
#
# existence:platform:kind:algorithms
#
# - "existence" can be "EXIST" or "NOEXIST" depending on if the symbol is
# found somewhere in the source,
# - "platforms" is empty if it exists on all platforms, otherwise it contains
# comma-separated list of the platform, just as they are if the symbol exists
# for those platforms, or prepended with a "!" if not. This helps resolve
# symbol name variants for platforms where the names are too long for the
# compiler or linker, or if the systems is case insensitive and there is a
# clash, or the symbol is implemented differently (see
# EXPORT_VAR_AS_FUNCTION). This script assumes renaming of symbols is found
# in the file crypto/symhacks.h.
# The semantics for the platforms is that every item is checked against the
# environment. For the negative items ("!FOO"), if any of them is false
# (i.e. "FOO" is true) in the environment, the corresponding symbol can't be
# used. For the positive itms, if all of them are false in the environment,
# the corresponding symbol can't be used. Any combination of positive and
# negative items are possible, and of course leave room for some redundancy.
# - "kind" is "FUNCTION" or "VARIABLE". The meaning of that is obvious.
# - "algorithms" is a comma-separated list of algorithm names. This helps
# exclude symbols that are part of an algorithm that some user wants to
# exclude.

Make a number of changes to the OS/2 build. Submitter's comment below. PR: 732 Submitted by: Ilya Zakharevich <nospam-abuse@ilyaz.org> Submitter's comment: This patch: a) Introduces a new file os2/backwardify.pl. b) Introduces a new mk1mf.pl variable $preamble. As you can see, it may be used also to move some OS-specific code to VC-CE too (the the first chunk of the patch); c) The DESCRIPTION specifier of the .def file is made more informative: now it contains the version number too. On OS/2 it is made conformant to OS/2 conventions; in particular, when one runs the standard command BLDLEVEL this.DLL one can see: Vendor: www.openssl.org/ Revision: 0.9.7c Description: OpenSSL: implementation of Secure Socket Layer; DLL for library crypto. Build for EMX -Zmtd [I did not make Win32 descriptions as informative as this - I'm afraid to break something. Be welcome to fix this.] d) On OS/2 the generated DLL was hardly usable (it had a shared initialized data segment). e) On OS/2 the generated DLLs had names like ssl.dll. However, DLL names on OS/2 are "global data". It is hard to have several DLLs with the same name on the system. Thus this precluded coexistence of OpenSSL with DLLs for other SLL implementations - or other name clashes. I transparently changed the names of the DLLs to open_ssl.dll and cryptssl.dll. f) The file added in (a) is used to create "forwarder" DLLs, so the applications expecting the "old" DLL names may use the new DLLs transparently. (A presence of these DLLs on the system nullifies (e), but makes old applications work. This is a stopgap measure until the old applications are relinked. Systems with no old applications do not need these DLLs, so may enjoy all the benefits of (e).) The new DLLs are placed in os2/ and os2/noname subdirectories. g) The makefiles created with os2/OS2-EMX.cmd did not work (some mysterious meaningless failures). The change to util/pl/OS2-EMX.pl uses the variable introduced in (b) to switch the Makefiles to SHELL=sh syntax. All these backslashes are removed, and the generated Makefiles started to work. h) Running os2/OS2-EMX.cmd now prints out what to do next.
